Help?

Hi All,

I'm trying to create a simple system on arduino using a stepper motor, a dc motor and a servo.

I need the system to soft start.

Any help would be greatly appreciated :slight_smile:

Thanks.

I need the system to soft start.

Whatever that means.

soft start - needing the dc motor to start slowly and accelerate to a faster speed.

i have no code or wiring done as im unsure as to what to do.

its a project

i need to simulate a glass engraver program.

all im being told is that the system should soft start, and the grinding wheel should be brought into contact with the glass. (simulated using a servo and a dc motor i think)
and the stepper motor simulates the carriage device moving the glass.

I could just use a little advice if possible.

thanks

Take a look at analogWrite. It will let you control DC motor speed using PWM. Note though that you'll need an external power supply and a transistor to switch it - the Arduino won't be able to directly power the motor.

Thanks, i’ll give it a bash.
